What is JavaScript Minification?
JavaScript minification is the process of removing unnecessary characters from JavaScript code and optimizing it for production. This includes removing whitespace, comments, shortening variable names (mangling), and optimizing code structure. Minified JavaScript files are significantly smaller and execute faster, improving website performance.

Pertanyaan yang Sering Diajukan
Is my JavaScript code private?
Yes. All processing happens entirely in your browser. Your JavaScript code is never sent to any server, making this tool 100% client-side and completely private.
Does minification affect functionality?
No. JavaScript minification removes whitespace, comments, and shortens variable names while preserving the exact same behavior. The minified code will execute identically to the original in all environments.
What is variable mangling?
Variable mangling is a minification technique that renames local variables to shorter names (like a, b, c) to reduce file size. Only local variables are mangled — global variables and exported names remain unchanged to maintain compatibility.
